You hear people say it.  Usually in a whisper:  "She's a cat lady"....   We all know one or two 'cat ladies'.  They would do anything for their kitties.  They buy more cat supplies in a week than groceries.  They leave their house smelling like cat litter (okay, maybe that's stretching it, but you get my point).

Obviously, real cat-people aren't the stereotypical old curmudgeonly widows in wood-framed houses with rocking chairs on the porch that are coo-coo for the mee-nuu:  this one seems to be quite a deb.
